INTEGRAL WATER REPELLENT ADMIXTURE

W-33 is an integral water repellent liquid admixture used in concrete blocks, pavers, roof tiles, and related precast, as well as mortar and stucco mixes. W-33 provides added water repellency, and aids cement hydration to provide increased compressive strengths and improved freeze thaw resistance. W-33 is formulated to reduce cracking, crazing, efflorescence, surface bleeding, and to help provide uniform color to pigmented mixes. W-33 is viscosity modified, allowing the active ingredients to remain in the concrete matrix and not separate or float to the surface during mixing.

BENEFITS:

Reduced moisture absorption

Reduced efflorescence & surface discoloration stains & deposits

Non-corrosive

Mold life extended by reduced concrete friction

Corrosion inhibitor of steel reinforcement

Improves plain and pigmented mixes

Compatible with other admixtures

COMPOSITION: Viscosity modified stearate-based solution. W-33 does not contain any calcium chloride or intentionally added chlorides that would initiate or promote corrosion of reinforcement steel, or contribute to efflorescence.

TECHNICAL DATA: W-33 is compatible with most mineral and chemical components common to Portland cement, calcium alumna cement and calcium sulfate (gypsum).

DIRECTIONS FOR USE: It is recommended that the W-33 be added directly to the mixing water. Dosage is 1 quart (32 ounces) per bag of Portland Cement (2080 ml per 100 kg). Add 16 oz per 100 lbs. of hydrated lime (1040 ml per 100 kg). Higher dosage rates will improve both bond strength and absorption reduction.
